This document outlines a proposal for the development of a device dedicated to monitoring the health and physical activity of athletes. The realization of this device leveraged the Arduino UNO microcontroller, and empirical trials have yielded encouraging results. The device was meticulously engineered with the primary objective of scrutinizing vital functions, encompassing heart rate, blood oxygen saturation, body temperature, lung capacity, and electromyography (EMG) for a comprehensive assessment of muscle activity. Furthermore, spirometry has been integrated to quantify lung vital capacity. This endeavor heralds pioneering prospects in the realm of health and fitness surveillance, proffering potential advantages not only to athletes but also to the broader populace.

The assessment of microscale biomechanical characteristics provides crucial information about the interplay between forces and tissue stiffness during development. These forces can regulate tissue dynamics and organogenesis. Many methods such as atomic force microscopy, optical tweezers, and optical coherence elastography have been utilized to extract mechanical parameters. However, these techniques often lack sufficient resolution or require external forces that involve contract, which can disrupt mechanosensitive cells and tissues. In this study, we have used a high-resolution Brillouin microscopy system enabling mapping of the stiffness of zebrafish embryos at cleavage periods 1 hour post fertilization (hpf), 1.75 hpf, and 2.25 hpf before and after a 1-hour cold treatment at 5℃. The axial and transverse resolution of Brillouin system was 2.3 and 1.8 µm, respectively, enabling cellular-level imaging of the zebrafish embryo mechanical properties. The results show that zebrafish embryo anomalies caused by the cold treatment were correlated to changes in the Brillouin frequency. The results show that the longitudinal modulus across the yolk has increased, and two various layers with different Brillouin frequency shifts at the blastomere are clearly observable. Furthermore, the results show an increasing stiffness at the interface of the blastomere and yolk regions, where the yolk syncytial layer (YSL) forms during early cleavage stages between the ninth and tenth cleavages, which is when the embryo has 512-1024 cells. © 2025 SPIE.

In this study we monitored indoor carbon monoxide (CO) levels for ~50 homes over two seasons in the Denver metropolitan area as part of the Social, Justice, and Environmental Quality-Denver initiative (SJEQ-D). These homes were chosen from disproportionately impacted neighborhoods and were impacted by a major freeway construction upgrade in close proximity to these neighborhoods. The results from the suggest that ~10% of the homes in each cohort had consistently low levels of CO (daily averaged values above 3.5 ppm) and ~20% of the homes also consistently showed episodic peaks above 9 ppm throughout this yearlong study spanning three different seasons. The results from this study underline the need for increasing awareness regarding the prevalence of low levels of CO exposures at homes since concentration at these levels could impact the overall health of residents especially pregnant women and sensitive populations. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference program and Proceedings.

Risk Allocation Preferences in Indonesian Electricity Public-Private Partnership Projects: A Conjoint Analysis

引用

IEEE engineering Management Review 2021年第3期49卷 154-174页

作者： Hartono, Budi Ghifari, M. Dzaki Agung Dianita, Orchida Industrial Engineering Program Mechanical and Industrial Engineering Department Faculty of Engineering Universitas Gadjah Mada Yogyakarta5528 Indonesia

This article investigates the risk allocation preferences of Indonesian government agents within a public-private partnership scheme in electricity infrastructure projects. A full-factorial conjoint analysis is employed by introducing three groups of risk factors, namely, 'Policy,' 'Legal,' and 'Project residual' risks, to form eight distinctive scenarios. A total of 37 respondents from a government agency and other public agencies participated in the experiment, and two distinct clusters within a single party (public entity/government) emerged. The two clusters agree on the order of importance of risk preferences but disagree on nearly everything else. The clusters diverge in the magnitude of risk importance, risk preference scores, profiles, and the most preferred scenarios. This article also determines that the risk preference profiles of both clusters do not consistently follow the optimum risk-sharing principles. Moreover, this article elaborates on the scientific contributions and practical implications of the findings. Results provide essential insights into the risk allocation preferences of the public agents. The findings contribute to the development of mutual understanding between the public and private entities. © 1973-2011 IEEE.

In this article, we harnessed biomedical applications in laser-assisted etching long-period fiber gratings (LLPFGs) sensors, subsequently deploying them within the realm of biomedical applications. The primary aim of this study was to devise a sensitive method for the detection of antigen-antibodies associated with rheumatoid arthritis (RA) using LLPFGs. Sensing the antigen binding took place on the surface of the optical fiber through a self-assembling process. Given the inherent limitations of conventional rheumatoid factor (RF) testing in terms of specificity, we introduced an innovative serum-based approach geared toward the identification of anti-cyclic citrullinated peptide (Anti-CCP) antibodies. This method exhibited an impressive diagnostic accuracy rate of approximately 80% for RA cases, coupled with an exceptional specificity level of 98% for individuals without RA. The incorporation of LLPFGs in the detection of RA antigen-antibodies presents a highly promising avenue for enhancing the precision and reliability of RA diagnosis. Furthermore, this research aligns closely with the United Nations Sustainable Development Goal (SDG)3, which strives to promote well-being across all age groups and advance sustainable development by addressing health-related challenges, including the accurate diagnosis of diseases like RA. © 2023 IEEE.

Walking, jogging, or leaping can be done with exceptional plantar comfort thanks to modern athletic footwear. On the other hand, a perceptual illusion is produced when harmful plantar loads cause minimal felt plantar discomfort. This leads to insufficient impact-moderating behavior and subsequent injury. Sports footwear goods are in high demand due to the notable increase in physical activity. The footwear business has had to increase product variety, shorten timeframes for product development, and offer customized goods in order to stay competitive. To measure the functionalities of athletic footwear, evaluations are essential in product development, developing prototypes, biomechanics, and other domains. These include the mitigation of impact forces during motion, traction, and motion control. In this work, the level of optimum athletic performance was determined for certain Indian-based footwear brands. Five athletic footwears from some of the leading Indian footwear manufacturers were selected for slip risk assessment studies in an athletic activity flooring. Shore A hardness was measured with the help of a durometer for all the athletic footwear selected for the study. The heel tread contact area of all the athletic shoes was also determined prior to the questionnaire survey and athletic evaluation by the participants. The evaluation was performed on the flooring of a badminton court. The participants were asked to wear the five selected athletic footwears and then perform their practice session accordingly. Their responses were recorded which included the attributes from footwear comfort, slipping probability and ease of athletic effectiveness. On the basis of these feedback, the most optimum footwear outsole tread pattern was shortlisted. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
